তড়িৎ রাসায়নিক কোষের emf = ?i. E° Anode(ox) + E°Cathode (Red) 11. E Cathode(Red) - E°Anode (Red) 111. E° Anode(ox) - E°Cathode (Red) নিচের কোনটি সঠিক?
Choose the right option among the alternatives – A thyristor goes into full conduction in its forward direction when anode/cathode/gate is positive with respect to its anode/cathode/gate and a turn-on voltage or current signal in the form of a pulse is given to its anode/ cathode/gate.
Given below are four jumbled sentences. Out of the given options pick the one that gives their correct order. A. You’ve probably noticed, with great disappointment, that the battery doesn’t seem to last as long as it did when it was brand new. B. Partial charging is just fine for lithium-ion batteries and can actually have some positive benefits for cell longevity. C. Smartphone users are forever in search of longer battery life, but unfortunately, battery capacity inevitably declines with age. D. However, one thing you can do to prolong the life of your battery and handset is partial charging.
